FIELD OF THE INVENTION

The present invention relates to bags made from medical-grade paper for sterilization with sterilization-process indicators and pigmented-adhesive based safety features, which is easy to handle and use and can be used to the store materials more particularly surgical medical material.

BACKGROUND OF THE INVENTION

The use of all previous surgical medical material to its use needs to be sterilized. These different types from instruments and mechanical pieces are placed within a sterilization bag that has a region that is permeable to the gas but impermeable to the germs and the bacteria. Later to seal the bag, the sterilization is realized with a method using steam of high temperature, ethylene oxide gas, (EOG) and similar. After the sterilization of the instruments until their use in surgery, the instruments are stored within the bag, and during the surgery or the treatment, the bag is opened and the instruments are used.

At present the designs of existing bags in the market present some disadvantages as it is the fact that the access to the material sterilized placed inside the bag does not allow being of efficient and fast way because the bag lacks devices and necessary fittings for it. Another disadvantage of the present existing designs is the fact that between the used materials they are tweezers and bistouries of weights and forms that break the bags that lack a sufficiently resistant bottom for these. In addition another disadvantage is the fact that they lack visual indicators that allow to visualize if the bag is perfectly sealed and indicators that allows to distinguish the type of sterilization to that they were put under and if the sterilization were carried out in correct form, to guarantee so much the security in the seal of the bag like in the sterilization process.

The patent application EP 1550466A relates to a sterilization bag used to store and to sterilize the medical instruments that have acute edges in which the lateral edges and greatest lower bounds are of are of a material of permeable type to the gas and to the steam and of a material adhered to an opening that is in a least upper bound of this, but this is different from the bag of the present invention.

The Mexican patent No. 178951 protects a bag for sterilization of material, which incorporates a device for fast and safe opening of the bags once the material was sterilized, but also is different from bag of the present invention.

The Mexican patent application 1998/00678 protects a bag for sterilization and conservation of material, that is similar to bag of the present invention, it is constituted by a piece of flexible material as paper, which presents a rectangular configuration, closed by its greatest lower bound with a double or triple bottom, two lateral sides which present rollings or bellows respectively; a part superior, which constitutes the mouth or entrance to bag to introduce the material to sterilize, in which a cut sawed to all wide it of this can be appreciated, counts in the profile of the rolling with a thread that is hidden by the internal part of this profile to open the bag with greater rapidity and facility, but this bag is different from bag of the present invention because bag of the present invention in its greatest lower bound presents a double bottom, but this double bottom counts at inner thermoweldable pigmented-adhesive sealed for its hermetic closure, this pigmentation of the adhesive allows us to visualize if it is or no perfectly seal, guaranteeing its total hermetic closure, in the frontal superior part in addition counts with one toe (with easy opening with finger) in the central part for easy opening in the filling, in the part frontal superior and reverse account also with a sawed edge to avoid that the personnel who uses them can cut itself, but in addition the part to come off the thread is straight and no sawed consequently the obtaining of the segment of paper is facilitated of surprising way to its opening later to the sterilization, avoiding with this the difficulty in its opening, in addition it counts on an inner thermoweldable pigmented-adhesive for his closing in the superior part, this pigmentation of the adhesive allows us to visualize if he is or not perfectly sealed, guarantee its hermetic closure and sealing thereof, the bag is closed longitudinally with a double line of pigmented adhesive, that guarantees a double security of seal, this pigmentation of adhesive allows us to visualize if it is or not perfectly sealed, it counts in addition on two indicators of sterilization that change of color depending on the sterilization process carried out on the bags, contains legend and instructions of use in ink water based, this ink water based has the purpose of identifying if there is flight of water or steam in the sterilization process if the ink is run, reason why this invention solves problems and has advantages that are not solved with the bag of the patent application 1998/006678, reason why bag of the present invention is new and inventive in the light of the present document.

The patent Mexican application 1999/001855 protects a procedure to apply to a chemical agent with germicidal characteristics to the medical grade paper for the manufacture of bags of paper, mixed bags, etc., which will avoid that these packages serve like vector or transport of microorganisms present on the environment or by manipulation.

This procedure comprising the following steps: a) The impregnating on the surface of the medical grade paper of paper weight between 30 up to 100 g/m² with an alcoholic solution of triclosan from 0.2% to 3.8% or a chloride aqueous solution of benzalconio from 0.2% to 3.8%, which must still remain after to carry out the sterilization process; b) The impregnating of the step a) is carried out by impression by flexography or by means of photogravure or by covering and c) the drying is realized to a temperature of 30° C. until 190° C. for a chloride aqueous solution of benzalconio and 30° C. until 70° C. for an alcoholic solution of triclosan.

The bag of the present invention has new characteristics of design and manufacture that contributes to solve the problems that present the used present bags for sterilization of material, reason why in the light of previous documents it is new and inventive.
